According to Joel Spolsky of "Joel On software", some Microsoft 
technical writers misunderstood a key term in Charles Simonyi's paper 
describing what came to be known as "Hungarian Notation".  Simonyi 
inappropriately used the word "type" when he meant "kind", and "type" 
was interpreted to mean "data type", like integer, float, and so on, 
when he'd intended it as a prefix to signal the _kind_ of thing, like 
"ix" for indices, "col" for variables containing column numbers, and 
"rw" for variables containing row numbers.

Joel describes how Hungarian notation got wrecked in "Making Wrong Code 
Look Wrong" (http://www.joelonsoftware.com/articles/wrong.html).
